The agreement announced Wednesday crosses a big item off the Cubs' to-do list, considering he had an expiring contract.
The extension comes with the Cubs wrapping up one of the greatest seasons in franchise history and their attention clearly fixed on winning their first World Series in more than a century.
They reached 100 wins for the first time since 1935 and were a major league-leading 101-56 heading into Wednesday's game at Pittsburgh. Chicago clinched the best record in the majors with more than a week left in the regular season.
